Twenty three people who had eaten at a San Diego County restaurant on February 16 became ill with abdominal cramps and diarrhea. The illnesses had been caused by Salmonella Enteritidis. The eggs used to make the hollandaise and bearnaise sauces were the implicated food source. The Salmonella Enteritidis was indistinguishable from the strain of Salmonella Enteritidis that had been isolated in a Los Angeles County egg-based outbreak that had occurred in January. All isolates were phage type 13a and plasmid profile type 2. The eggs in both outbreaks originated from the same distributor.
